I have a radlistbox
I can add to the list box
I can remove from the list box
What I cant for the life of me work out how to do is how to edit an entry in radlistbox in place.

I want to be able to change and save the text of a radlistbox item (preferably with AJAX)...

If anyone can point me to an example, pointer or guide as how to get started with this would be great.

Thanks....

[Solved] Issues with DetailTable Admin form

Hi All,

I've been trying to figure this out for a while and not having much luck hence this posting.

I have a grid that has a subgrid for each row using detailtables, both levels are editable. Because I have checkboxes in the admin form of each level I need to setup the value of any new rows in the InitInsert event and all of this works nicely.

I have two issues now. The fist issue is that I need to conditionally hide the checkbox (and potentially other fields) in the child level depending on a value in the parent level. The second issue is that I want to have a checkbox present on the form which when ticked and the record is saved a new insert form opens up - thus saving the user from clicking a on the new item icon again.

Re the first issue I have the following in the ItemCommand event for the grid,

...

ElseIf e.CommandName = "InitInsertElement" Then

e.Canceled = True

Dim newValues As System.Collections.Specialized.ListDictionary = New System.Collections.Specialized.ListDictionary()

newValues("IncludeInTotal") = True

'IF THE CostType CELL IN THE PARENT ROW = UnitCost THEN HIDE THE uxIncludeInTotal CHECKBOX ON THIS INSERT FORM

DirectCast(e.Item, Telerik.Web.UI.GridDataItem).ChildItem.NestedTableViews(0).InsertItem(newValues)

ElseIf .....

Re the second issue I have tried the following code to trigger the insert form to reopen but although the itemcommand is triggered the insert form does not load.

If CType(editedItem.FindControl("uxAddNewAfterSave"), CheckBox).Checked Then

Dim parentItem = CType(e.Item.OwnerTableView.ParentItem, Telerik.Web.UI.GridDataItem)

parentItem.FireCommandEvent("InitInsertElement", String.Empty)

End If

Any help please?

Regards,

Jon

Change color of button on hover

Hi

I am trying to modify slightly the color of the button on hover when using the form decorator with 'Hay' skin.
Tried a css file technique (see below) that worked with an earlier version of the controls, but it doesn't work now (Q2 2010 release).
Can you tell me what I should be using instead?
Thanks
Clive

a.RadForm_Hay:hover .rfdInner {color: #ACB936 !important;}

Grid Column rename/remove

Hi,

I want your help to the following problem.

I have a grid which calls an OnNeedDataSource event to fetch data. The grid columns and data are automatically created based on the list(Of Object) I pass to the grid datasource. The problem I have is that I want to REMOVE and RENAME some columns from the grid but I want to maintain the way the grid works now. How can I rename the column headers of the grid or make them visible false from code behind? From the aspx file I can't do anything because in the ...<MasterTableView><Columns>... tag I don't include any data.

Thanks
George

Filter by unique name - not by Datafield/Displayname does not work

Hello,
I am trying to filter a column in a radgrid with a custom filter template, based on the id´s of the objects and not the display names (in some cases we have entries with the name / display name)

My Code is:

<telerik:GridBoundColumn AllowFiltering="true" AllowSorting="true" DataField="Accountrole.Name"

HeaderText="<%$ Resources:Administration,Role %>" UniqueName="Accountrole.RoleId">

<FilterTemplate>

<telerik:RadComboBox ID="RadComboBoxRole" DataSourceID="RoleDataSource" DataTextField="Name"

DataValueField="RoleId" AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("Accountrole.RoleId").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="RoleIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="<%$ Resources:Basic,All %>" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function RoleIndexChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("Accountrole.RoleId", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

Unfortunately the filtering does not work because my entity data source get athe following filterexpression from the grid (seen in debug mode):
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.Name = \"1\")"
but it should be:
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.RoleId= \"1\")"

How can I tell the Grid to generate the correct filter expression?

Thanks in advance!

How can I access to a control exists in a EditItemTemplate from a custom event handler ?

Hi,

I want to set a value in a control exists in a GridTemplateColumn, I've read many threads here about it and I figure out that I must use ItemDataBound event instead,
but actually I can't, because I have a control shows a popup and the popup returns a value by a callback in the server,
so how can I deal with this situation?

The code:

protected void MyCustomControl_ItemSelected(string returnedValue)

{

var control = (RadGrid1.EditItems[0] as GridEdittableItem).FindControl("MyCustomTextBox");

if (control != null)

{

control.Text = returnedValue;

}

Thanks in advance.
